UserMixin在模型上进行子类化。你还应该添加一个user_loader
from flask.ext.login import UserMixinfrom yourapp import login_manager@login_manager.user_loaderdef get_user(ident): return User.query.get(int(ident))class User(db.Model, UserMixin): id = db.Column(db.Integer, primary_key=True) ### yada yada, you know what goes here
